The cycle repeats

Dunno if anyone could relate but I'm at a point at life were im not attached to anything and think of it as a cycle of repeating the same thing day after day I graduated recently and only work Wednesday Thursday and I've done this ritual I call it nerdy ik but Thursday night I blast my music loudly at night and just have fun but the next day I do a daily check list wake up 9:30 am shower take care of animals and workout every 3 hours and clean room every 2 hours besides that I don't really do anything besides play my game or listen to music but recently I've felt the worst after my dog died my mother told me that she's gonna go take him to the vet I said okay them she went and I went to work i came back at 3 and she casually says the dogs dead and I just broke didn't really looked upset but I still had to work so i just casually continued my day like nothing happened but recently ive been so upset about it i used to wake up take him out and we would just chill in bed all day but now its different it's just me i thought it would be better to replace the feeling so i bought 2 birds parakeets and its just not the same im 16 going on 17 and I have nothing really important or have sentimental values mostly because when i talk about my problems my mother says i dont have time for your teenage life crisis and my sister just makes fun of me so thsts why I'm here does anyone feel the same am I weird or is this just life?
